Invictus, Thank you for your civil response to my perhaps intemperate questions. Funnily enough, I would rank those Goldmund turntables as among the worst, most over-rated DD turntables I have ever heard, starting with their very badly implemented suspension systems. And their drive systems don't compete for engineering sophistication with the best Denon and Technics vintage DDs, in my opinion. I have yet to hear the 1200G, but the 1200G and the 10R both incorporate coreless motors. I have found that I tend to prefer DDs driven by a coreless motor, too. Among vintage DDs, this includes the Kenwood L07D and the Victor TT101. (There are more, Including the Yamaha 2000GT, but I haven't heard them.) Oddly enough, just based on what I know about SME turntables, I imagine that the SME design philosophy results in a turntable that has many of the qualities I like about DD turntables. If you found that you prefer the SME to the 1200G, that is a good head to head comparison, except, assuming you own one of the better SMEs, the cost is 2-3X that of the 1200G.
Fremer, who wrote the paragraph you or someone else cited critiquing the servo system used in DD turntables, more recently went on to write a glowing review of the SP10R, calling it one of the best turntables he has ever heard and also showing graphically that it was the most speed stable turntable he has ever measured. Somehow, he forgot to complain about the servo mechanism in that review. (Or, without checking the review, perhaps the spiel about the servo system was built into the SP10R review.) But negative reference to the servo system in DD turntables is a common device used by those who want to sell belt-drive or who have a pre-determined bias of some kind. DD turntables CAN have a coloration, which I think is much more due to either EMI emanating from the motor or to motor cogging. (Hence perhaps the reason that coreless motors seem to impart a more "continuous" and musical sound.) I think it's important to shield the cartridge from EMI, and the shielding effect may be the major reason why a lot of people swear by copper platter mats, etc.
And finally, nearly all modern belt-drive turntables are nowadays using a drive system that incorporates a feedback system to maintain speed stability. Witness the recent popularity of the Phoenix Engineering products in the US. How ironic is that? If the belt is at all compliant, this could in theory play havoc with speed stability, because if the drive system "sees" that the platter is slow (for example), it will signal a correction. The resulting torque bump from the motor will partly be used up in stretching the belt before the platter speed can respond. And etc. This back and forth is potentially worse than DD, because of belt compliance, if indeed there is any problem at all with DD in this regard.
